This document contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing speciÞcations for the PowerQUICC IIª MPC8260 communications processor. Changes since the last update (rev 0) are marked by change bars in the left margin. The MPC8260 electrical speciÞcations are preliminary and many specs are from design simulations. These speciÞcations may not be fully tested or guaranteed at this early stage of the product life cycle. Finalized speciÞcations will be published after thorough characterization and device qualiÞcations have been completed.
